PROCESS AND DESIGN FOR ADDITIVE MANUFACTURE OF PINCERS AND NIPPERS

Resumen de: US20260070285A1

Described is a design and process for additive manufacture of pincers or nippers. 3D printing allows the rapid and efficient manufacture of individually designed tools for increased customer satisfaction and reduction of waste and inventory. This invention overcomes problems with existing manufacturing practices such as waste, lack of variability and user ergonomics. The problem to be addressed is that these tools can be subjected to very high flexural pressures and the design must be unique. For example, even steel nipper handles can bend under such pressures, so polymer tools must be specially designed and not just copied from the existing design and technology. For the end user, the design and manufacture of the nipper handles can be configured to the users'specifications and produced individually and cost-effectively by innovative additive manufacturing techniques. The materials used for the handles are of a specially configured, individually 3D printed polymer material which can be various sizes, shapes and a variety of colors, as well as contours or individualized finger grooves for comfort and stability. For the manufacturer, custom pincers or nippers can be individually produced to a user's preferences with small changes in programming, inexpensive materials and no waste. The configuration of the handles can be a larger, lighter, and more comfortable in shape and size. Infill can be easily designed to reinforce high stress areas while reducing weight which monolithic

Electrochemical additive manufacturing (ECAM) enables precise, layer-by-layer fabrication of these structures, allowing customization for different flow regimes and heat flux profiles.

METHOD AND SYSTEM FOR THREE-DIMENSIONAL MODELING OF STOCHASTIC VARIATIONS OF LITHOGRAPHIC PROCESS

Resumen de: US20260064012A1

A method and system for 3D modeling of stochastic variation of a lithographic process. The lithographic process is subject to random stochastic phenomena, with the resulting stochastic randomness potentially becoming a major challenge. The stochastic phenomena are modeled using a stochastic model, such as a random field model, that models stochastic randomness. To extend the application of the stochastic model to predict 3D aspects and increase the accuracy of modeling, the stochastic randomness for each level of a plurality of levels discrete from one another in a resist thickness direction may be modeled and analyzed across the plurality of level to generate a 3-dimentional distribution of the stochastic randomness. In turn, indications of 3-dimentional distribution of the stochastic randomness may be used to modify one or both of the light exposure and resist parameters in order to reduce the effect of stochastic randomness on the lithographic process.
